Stainless Steel Flanges

ASTM A182 Weld Neck Flange, Check Stainless Steel Pipe Flange Price List

Stainless Steel Flanges are made up of different stainless steel materials. There are different grades to the stainless steel depending on the material composition and the mechanical properties vary. Navstar Steel is a leading manufacturer and supplier of these flanges. The ASTM A182 Weld Neck Flange are made up of a super austenitic material that has good corrosion resistant properties with low carbon in its composition. The applications include utility scrubber assemblies. The flanges are also used in acid production and fertilizer production plants due to its corrosion resistance.

Check SS Blind Flange Dimension, Ferritic Stainless Steel Flanges Manufacturers In India

The Stainless Steel Pipe Flange is used to close a pipeline in these industries. The blind flange can be permanently fixed with welding or temporarily fixed by bolting for easy maintenance and removal. These flanges come in different sizes ranging from ½ inches to 48 inches in nominal bore size. There are also different types such as the SS Blind Flange Dimension belonging to different pressure classes. The pressure classes vary from 150 to 2500 and PN6 to PN64. These indicate the maximum pressure each flange can withstand while in operation.


The SS Flanges are welded neck raised face flanges. The welded neck supports these flanges to hold the pipes in place while welding. The raised face allows for maximum attachment for either welding or space for bolts and nuts. There are different brandings and standards of flanges such as the Stainless Steel Threaded Pipe Flange which are known for their strength, corrosion resistance and quality. We supply all kinds of stainless steel flanges in different standards, specifications and dimensions. Please contact us for more information on the SS Slip On Flanges and the prices. We are Leading Stainless Steel Flanges Manufacturers In India.
